Alkylated intermediate of cyclo-alkanes for stabilization of paraffinic jet fuels under pyrolytic conditions

The thermal stability of linear alkanes, such as tetradecane, in the pyrolytic regime is enhanced by the addition of cyclo-akanes, in particular decalin. Based on the product distribution from the thermal stressing of their mixtures, decalin was found to target primary radicals, particularly by a sharp reduction in the n-alkane products in relation to that of the 1-alkene. This thermal interaction has been further examined by GC/MS analysis, which revealed the formation of alkylated intermediates of decalin that stabilizes the paraffinic species in the pyrolytic regime.
